High Bright Displays
In the old adage, seeing is believing. In today’s modern industrial applications, seeing is more than that. It’s the essence of control, since the human machine interface (HMI) involves the presentation of visual information. That’s why there’s such a demand for high bright displays in highly customized industrial computers and in stand alone industrial monitors.
Such displays have a brightness of at least 350 candelas per square meter, or nits, which is required for operation in transportation, medical, military, semiconductor and other areas. For those industrial applications, liquid crystal displays, LCDs, are the best choice. They have the needed brightness, meet viewing angle requirements, come in a variety of sizes and form factors, and offer different mounting options. Their prices are dropping as manufacturing matures and volumes increase. Furthermore, technology advances, such as transflective displays, promise even better performance in a variety of lighting conditions.
However, not all LCDs are the same. In industrial applications, such features as display size, power supply, and location of on-screen display, or OSD, controls have to be considered, along with certifications for operation in harsh environments. This white paper will cover display technologies, indicate which is best for industrial applications, discuss market and technology trends, and finally make recommendations about what to look for in a display.
